[libmicrohttpd] gnutls_init_flags_t error

[Erik Smith]

I'm seeing this error when building MHD on 0.9.66 on linux.  The gnutls
version is 3.3.8.  Ideas?

daemon.c: In function ‘internal_add_connection’:
daemon.c:2512:7: error: unknown type name ‘gnutls_init_flags_t’
       gnutls_init_flags_t flags;
